  1. Positron Emission Topography (PET) Jhazz, Emiri, Christian

  2. What is PET?

  3. PET scans

  4. PET study of Meditation with Buddhist monks (Davidson, 2004) Aim • To examine whether meditation affects the brain activity Procedure • 8 Buddhist monks who were highly experienced in meditation, and 10 volunteers who trained meditating for a week • All participants were told to meditate on love and compassion • PET scan was used to observe the number of gamma waves in their brain.

  5. PET study of Meditation with Buddhist monks (Davidson, 2004) Findings • Increase in the number of gamma waves in their brain during meditation • Constant gamma-wave production in the Buddhist monks after they stopped meditating Conclusion • Meditation has significant long-term effects on the brain and the way it processes emotions • Brain adapts to stimulation from the environment and/or the result of one’s own thinking

  6. Strengths and limitations
